According to Global Economic Prospects 2007: Managing the Next Wave of Globalization, in 2007 and 2008, growth in developing countries will probably slow, but still likely exceed 6 percent, more than twice the rate in high-income countries, which is expected to be 2.6 percent, said the report.

Meanwhile, the whole world gross domestic product (GDP) growth is estimated to have strengthened in 2006, coming in at 3.9 percent, compared with 3.5 percent in 2005.

On how globalization will shape the global economy over the next 25 years, the report's "central scenario" predicts that the global economy could expand from 35 trillion U.S. dollars in 2005 to 72 trillion dollars in 2030.

"While this outcome represent only a slight acceleration of global growth compared to the past 25 years, it is driven more than ever before by strong performance in developing countries," said Richard Newfarmer, the report's lead author and economic advisor in the Trade Department.

"And while exact numbers will undoubtedly turn out to be different, the underlying trends are relatively impervious to all but the most severe or disruptive shocks," he said.

Broad-based growth in developing countries sustained over the period would significantly affect global poverty.

"The number of people living on less than 1 dollar a day could be cut in half, from 1.1 billion now to 550 million in 2030. However, some regions, notably Africa, are at risk of being left behind.

Moreover, income inequality could widen within many countries, compounding current concerns over inequality between countries," said Franois Bourguignon, World Bank chief economist and senior vice president of Development Economics.
